Known issues by generation
The E28 M5, with its S38B35 engine, is renowned for specific maintenance considerations. Notably, timing-chain and chain-guide replacements are critical at 100-150k miles to prevent issues like chain rattle. Additionally, the six individual throttle bodies must be properly balanced for optimal performance. Age-related problems such as capacitor failure in the Bosch Motronic ML 1.x ECU can also occur, necessitating a rebuild or upgrade. Rust issues are common in salt-belt regions, particularly at fender lips and rocker-panel seams. Maintaining the original paint and verifying the BMW Motorsport Garching build-plate authentication are essential for collectors.
